    Study Notes

    Quantum Computing

    • Has the potential to revolutionize business computing due to its ability to process massive datasets at unprecedented speeds.
    • Can lead to breakthroughs in pharmaceuticals, logistics, and finance, where complex simulations and calculations are essential.

    Blockchain

    • Expected to expand beyond cryptocurrencies.
    • Can be used by businesses for secure and transparent supply chain management, smart contracts, and mitigating cybersecurity risks.
    • Attributes of decentralization and immutability make it suitable for these applications.

    Edge Computing

    • Becoming crucial in business computing due to the increasing number of devices connected in the Internet of Things (IoT).
    • Involves processing data closer to where it is generated, reducing latency and bandwidth use, and enhancing real-time data processing capabilities.

    Sustainable and Green Computing

    • Businesses are expected to adopt sustainable computing practices due to growing concerns over climate change.
    • Includes optimizing data centers for energy efficiency, using renewable energy sources, and developing eco-friendly hardware.

    5G Networks

    • Will significantly impact business technology with higher speeds and lower latency.
    • Enables more efficient remote working, improves IoT applications, and opens new avenues for mobile commerce and real-time data analysis.

    Cybersecurity

    • Importance is magnified due to increased digitalization.
    • Emerging trends include the use of AI for threat detection, adoption of zero-trust security models, and increased focus on data privacy regulations compliance.

    Distributed Processing

    • Refers to the use of multiple computers working together to perform tasks.
    • Enables more efficient data processing and resource utilization.

    Basics of Distributed Processing

    • Involves a network of interconnected computers that communicate and cooperate to achieve a common goal.
    • Components include multiple computer systems, a network connecting them, and software enabling communication and task distribution.
    • Tasks are divided into smaller parts, distributed among the computers, and results are communicated back to a central system or coordinator.

    Types of Distributed Processing

    • Client-server systems, where clients request services from centralized servers.
    • Peer-to-peer systems, where each node can serve both roles.

    Advantages of Distributed Systems

    • Scalability: easily scalable by adding more nodes.
    • Reliability: failure of one node does not cripple the entire system.
    • Resource Sharing: resources such as databases and processing power can be shared across different nodes.
    • Flexibility: offers flexibility in terms of location, hardware, and software choices.
    • Performance: can process large volumes of data more quickly than a single computer.
    • Cost-Effectiveness: can be more cost-effective, allowing for the use of cheaper, off-the-shelf hardware and open-source software.

    Backing Storage Solutions

    • Refers to methods and devices used to store data in a non-volatile manner.
    • Crucial for data integrity, security, and accessibility in business.

    Types of Storage Devices

    • Hard Disk Drives (HDDs): traditional storage devices that use magnetic storage, known for large storage capacity and cost-effectiveness.
    • Solid-State Drives (SSDs): faster than HDDs, use flash memory to store data, and have no moving parts.
    • Network-Attached Storage (NAS): dedicated file storage device that provides multiple users and client devices access to data through a network.
    • Cloud Storage: involves storing data on remote servers accessed from the internet, offering flexibility, scalability, and remote access.

    Types of Storage Devices Used in Businesses

    • Direct-Attached Storage (DAS): physical storage devices directly attached to a computer or server, offering fast data access but limited sharing capabilities.
    • Storage Area Network (SAN): high-speed network that provides block-level network access to storage.
